Mostly Permanent Magnet Motor with minimal Input Power

Hi, point of the arrow is North. Travels North to South.

I've confirmed this prior to my above post.

What I'm asking here is, if we look at the direction of the points (see below coil ends), to me it looks like both coil ends have the arrow points going in the same direction, how can this be?
How do you explain this?

ADDED  Unless the coil ends are top and bottom?... then I don't know why this is called a Solenoid coil!
Isn't a solenoid usually longer between its ends?

This is what I wrote in my previous post:

In the illustration, that magnetized direction is in the center (centre if you are Canadian) of the solenoid, so bottom to top.

So yes, the field is VERTICAL and the windings are horizontal.

The "poles" are on the top and bottom, not on the sides as you are illustrating.

The term "Solenoid" is usually associated with a long thin coil, yes.

However, it makes little difference what you call it, a coil is a coil, and the flux diagram is essentially the same no matter the dimensions.

Okay

if we look at your first illustration (attached below) of an energized solenoid and we follow the arrows, how can we tell which end will be North or South?

Okay, we are now in agreement!

The below now illustrates what I've originally observed, understood and shared. However, when originally shared I used Red an Blue block to show the positions of the poles but I can use arrows if that works better for the people.
Anyways, I don't see or understand it any differently now by seeing arrows then when I first understood it, so if anyone see it in a different way by using arrows please share what you see is different.

Thanks poynt for your effort of making it clear.
